Lamp shades of paper, fabric, or similar suitable material are generallyfitted on lamps such as table lamps or standard lamps by means of a wireframe which is especially adapted to the particular lamp shade, whichframe is placed loosely upon the frame or shade holder of the lamp. Thisway of mounting the shade is rather defective as the shade is quiteloose and therefore by being shaken or by the lamp being moved willrattle, sit wryly, or even drop off.

In accordance with the present invention a plaited lamp shade .is nowshaped so that it can be quite immovable direct on the frame or shadeholder of the lamp without the use of any special extra frame or otherspecial securing means. The invention is first and foremostcharacterized in that by means of bendings placed at an angle with theplaits the shade material is shaped so as to form a collar which can beled down into and secure the shade to a central opening in the frame.The tension of the plaits will secure the collar of the shade in theopening, so that the shade is held sufficiently fast for not rocking orbeing made to sit wryly or drop off when the lamp is moved orunintentionally shaken.

The spreading of the shade may be efiected by a spreading ring which e.g. may be formed by an edge or surface already situated on the frame,against which edge or surface the inner side of the shade treads.

In many frames the opening has an inwards bent edge which holds theshade especially well fast and which in accordance with a furtherdevelopment of the invention may be used for procuring a positivelocking of the shade to the frame. This is in accordance with theinvention attained by the inner termination of the securing collar beingby a further bendin bent outwards, so that it may engage under the edgeof the central opening.

The securing collar may be produced by any suitable bendings of theshade material and may have a more or less complicated form, so that ifsuch be desired it may at the same time be used for decoration purposes.In connection with this the shade in accordance with the invention mayhave a securing collar at both ends so that the shade may be turnedup-end down and secured on the frame in both positions. By shaping thetwo collars differently the shade thereby gets two different appearancesaccording to the position in which it is placed, the collar which doesnot act as securing collar being situated below as a termination ortrimming collar along the lower free edge of the shade.

The invention is illustrated on the drawing on which Fig. 1 shows avertical section through the upper part of an embodiment of a shade inaccordance with the invention placed on a lamp indicatedschematically.

Fig.2 part of what is shown in Fig. 1 viewed from above,

Figs. 3 and 4 on a smaller scale another embodiment placed in twodifferent positions on a shade is to be placed on a frame secured to thelamp. In Fig. 1 the frame is shown in the form of a conical bearingsurface which by suitable means not shown is secured to a ring or .acorresponding holder, which may be secured to the lamp holder 1 Or onanother suitable part of the lamp. The frame has as is the use inordinary lamp frames a central opening 2 above. The shade 3 is producedof a suitable material, e. g. paper, parchment, fabric, or the like,which is bent into a number of parallel folds or plaits. At the upperend of the shade there is by bendings 4, which are at an angle to theplaits, produced an approximately cylindrical collar 5, which like aplug is led down into the opening 2 and thereby secures the shade to theframe. The spreading angle of the shade is in this embodiment determinedby the conical bearing surface of the frame, against which the innerside of the shade bears.

In this embodiment the shade is held fast in its place by the frictionbetween the edge of the openin 2 and the collar 5, which by the tensionof the plaits is held pressed against the edge, to which also thepressure of the shade against the lower edge of the bearing surface maycontribute. The opening 2 may have a somewhat inwardsbent andcontingently rather sharp edge which holds the collar securely fast.

In the embodiment shown in Figs. 3 and 4 the plaited shade 3 has asecuring collar at both ends so that it may be turned up-end down, suchas appears from the figures. The securing collars are here terminatedwith an outwards-turning bending 6 which engages under the inwards-bentedge of the frame openin 2. The frame is here shown in the form of aso-called standard frame which consists of a ring which at the top hasthe said inwards-bent edge and below an outwards turning collar, andwhich is carried by three wire stays only one of which is shown by 8 inFig. 3.

In order that the plaits and bendings may be produced with the necessaryaccuracy they are made after previously drawn or impressed foldinglines. These may be produced by hand or in a machine by known means.After the shade has been plaited and bent its two longitudinal edges aresewed together. As as further support of the attachment there mayespecially in large shades below be placed a ring of holes, throughwhich a cord is drawn. By the tightening of this cord the pressure ofthe shade against the'frame is increased, whereby the attachment isensured.

I claim:

1. A lamp shade for lamps comprising a. shade receiving frame with anupper central opening and spreading means engaging the inner side of thebody portion of the shade, said body portion consisting of pleatedresilient material and having at its upper end an integral pleatedcollar created by folding the material and adapted to be passed downinto said central opening, and securethe shade to the frame byengagement therewith owing to the elastic tension of the pleats.

2. A lamp shade receiving frame with an upper and spreading meansengaging central opening the inner side of the body portion of theshade, said body portion for lamps comprising a shade 4 by folding thematerial-and extendinginwards over the edge of said central .opening anddown into the same, said collar being adapted to obtain frictionalretaining engagement with said edge owing to the elastic tension of thepleats.

4. A lamp shade for lamps comprising a shade receiving frame with anupper central opening and spreading means engaging the inner side of thebody portion of the shade, said body portion consisting of pleatedresilient material and having at its upper end an integral pleatedcollar created by folding the material and extending inwards over theedge of said central opening and down into the same and outwards undersaid edge for obtaining a positive locking engagement therewith owing tothe elastic tension of the pleats.
